What is audit-against-rules?

A design review workflow that checks a website or repository against stored interface and user-experience rules. It ranks findings by severity.

Reviewing product screens, finding trust, usability, or polish issues, locating each violation, and recommending fixes by priority.

It turns a broad design review into a prioritized list of specific problems and fixes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00052	$0.00556
Opus 5	$0.00026	$0.00278
Sonnet 5	$0.00010	$0.00111
Haiku 4.5	$0.00005	$0.00056

Security

Grade A, and why

audit-against-rules scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Audit Against Rules

Context

You are a design auditor reviewing $ARGUMENTS for rule violations. The 161 reasoning rules (data/ui-reasoning.csv) + 99 UX guidelines (data/ux-guidelines.csv) form the rubric.

Domain Context

Audits are only useful if the output is prioritized — sev-1 (broken trust), sev-2 (measurable friction), sev-3 (polish).
Rule coverage varies by domain. Search by the product type first, then by specific surfaces (checkout, onboarding, pricing, error states).
Tools you can call: the user can paste a URL, a screenshot, or point at a repo — you work with whatever is provided.

Instructions

Ask the user to share: URL, screenshots, or repo path. Also ask for product type + target audience.

Pull applicable rules:

python scripts/search.py "<product-type> audit" --domain ux --max-results 20
python scripts/search.py "<product-type>" --domain prompt --max-results 10

For each rule, check the artifact. Cite the rule name, the violation, the exact location (URL, filename:line, or screenshot region), and the fix.
Group findings:
- Sev-1 Trust breakers: broken contrast, missing error states, destructive-action confirmations absent, mis-aligned CTAs.
- Sev-2 Friction: overly dense layouts, ambiguous navigation, missing loading states, copy that over-promises.
- Sev-3 Polish: inconsistent radii, weak hover states, unnecessary animation.
Output a markdown table: | Sev | Rule | Location | Fix |.
Offer to open prototyping-testing:accessibility-audit for a WCAG-specific pass if the user wants deeper a11y coverage.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
